3 At this time, libpeak supports x86, m68k, powerpc (PowerPC 32/64
4 bits and POWER), sparc and IA-64 processors.

6 List of platforms where libpeak is known to have compiled and passed
7 the test suite at least once (sometimes with warnings):

30 Please note that libpeak should be particularly efficient on:
31
32 Darwin 7.0+ (Mac OS X 10.3+)
33 - kqueue engine
34 - mach semaphores and good multi-threading support
35
36 FreeBSD 4.9, 5.1+
37 - kqueue engine
38 - good multi-threading support
39
40 Linux 2.6+
41 - epoll engine (be careful to have a recent glib)
42 - good multi-threading support only with a few threads, which is OK
43 for libpeak
44
45 The epoll engine is probably as good as kqueue except maybe for safe
46 signals handling. Current epoll implementation in libpeak behaves as
47 Level Triggered, but I plan to write later an Egde Triggered version
48 to compare them. Other comparative stats should be available online on
49 PEAK's web site one of these days.

51 Performance with Solaris
52 ------------------------
53 If you're using Solaris 8 or more, you should use the alternate LWP
54 threads library implementation (one-level model), which should be more
55 efficient with libpeak than the default two-level threads model. The
56 configure script doesn't enable them automatically for now, but you
57 can enable them easily by setting:
58
59 export LD_LIBRARY_PATH=/usr/lib/lwp
60
61 before launching the program that uses libpeak (see man pthreads).
